The users got double the capacity of a DD at the same speed. And it was 1.76 rather than 1.44. I think it wasn't that bad, except that of course HD drives didn't make it to mainstream Amigas, which was a real PITA. I remember people paying stupid prices at my place just to actually be able to read those msdos formatted 1.44 floppies into an Amiga.. > but I must admit that commodore already did something similar with the speed of IEC bus due to bugs in components... Right. That's what's called working things around. > BTW: i consider the PC as the worst machine ever made... And you are not alone. And for a reason too ;-) -- SD!
